1. A method of fermenting, wherein the method comprises:
a) providing a fermentable composition, wherein the fermentable composition comprises:
i) biomass, wherein the biomass comprises a solid component and a saccharide component; and
ii) a microorganism that can convert monosaccharide into a biochemical, wherein the microorganism comprises yeast,
b) exposing the fermentable composition to conditions to convert at least a first portion of the saccharide component into a biochemical via fermentation;
c) after performing step (b) for at least 12 hours,
i) exposing at least a portion of the fermentable composition to a disruption process to disrupt at least a portion of insoluble solid component; and
ii) during and/or after (c)(i), converting at least a second portion of the saccharide component into biochemical via fermentation.
